Bait-known that .1, JOHN C. Lows, acitizen ofthe UnitedStates, residingat Minot,

inthe county QflVard' and State of North 'iDakotadhave invented certainnew and useful '-'Improvements in Combined Phono-v graphsandTelephonea'of whi'ch'the follow- My inventiomrelates to improvementsin combined 'phonographs and telephones.

a My. invention embodies the combination of a phonograph with atelephone, by means of which a telephone call is automatically answeredby the machine at the station returns'tot'he starting position, andstops,

called, after which operation the machine and is in a condition torepeat, the opera-- tion, atevery subsequent call ofthe telephone. Theinvention enables the answering got the telephone calls automatically inthe I; absence of anyone at the station called, by placing upon themachine; a phonograph record, having thereon-a desired message tobodying my invention, I

In the accompanying drawings, forming a {part of this specification, and,in" which" like numerals are employed to designate like partsthroughout the same, i 2' Figure is a plan view (if a machineem- Figure2 s an end elevationqf same,

, Figure 4 is a maGli1n,. .v I Figure. 5 1s a transverse section takenon line 5+5of Figured, and, I I

Figure-6 is an enlarged side elevation of the sound box, and associatedelements. In the drawings, whereinfor the purpose of" illustrationis"shown a preferred 'embodiment of- Iny'invention, the numeral 10designates abox or casing, within. which is mounted a motor, such as aspringmotor or van electric motor, driving a train of gears 11. Thesegears are connected with a brake I disk 12,"rotating therewith. When thebrake disk is held against rotation, the train of gears. do not rotate.I I Arranged above the casing 10 is a hori- 'zontal. rotatable cylinder13, receiving its rotation from a shaft 14', having a pulley 15 rigidlymounted thereon. This pulley is drivenf by a lieltddengaging a pulley17,

to ,the person at the calling sta rearside elevation of; the-1 Thenumerals 18 and 19 designate feed and reverse shafts, which are arrangedabove the box, in parallel'relation to the cylinder .13; These shaftshave their ends journaled within bearings 20 and 21. The shafts 18 and19 are screw threaded throughout sub- ,stantially their entire length,asshown. Theshaft 18 receives its rotation from a gear 22, rigidlymounted thereon and this gear en gages a gear'23 r1'g1dly mounted uponthe shaft 19, and it is thus seen that the shafts 'the guidesh-aft- 26is a carriage 28, which cannot turn thereon, by virtue of a key 29,slidable in a :slot 30. The carriage 28 rigidly supports, an overhangingarm 31, carrying the diaphragm chamber or sound box 32.

The diaphragm chanibier' receives the usual diaphragm, having suitableconnection with thestylus lever 33, which is vertically adj'usted andcarries the stylus 34. The stylus lever is raised and lowered by means,of a" bell-crank lever pivoted at 36, to abracket 37, rigidly securedto the arm 31. This bell-crank lever is connected with a link 38,

which is shiftedby means to next .de-'

scribed."

v The carriage 28 has a tubular extension or hub 39, rigidly securedthereto, and this tubu- I lar extension pivotally receives a collar 40formed upon the central portion of a feed bar 41. Thisfeed .bar isprovided at its ends a with curvedh'eads 4:2 and 43, having screwthreaded recesses dfwhich engage the feed and reverse shafts 18 19, asshown. The collar 40 is provided in its top with a spring.

pressed bolt 45, for, insertion within reclearly shown in Figure5. Anupstanding inverted ll-shaped frame 48 is rigid y mounted upon the feedbar ,41, and projects above the same, and is pivotally connected withthe link 38, as shown at 49.

electro-magnet 50, and is retained in the normal position by a spring52. The armature 51 Carries a spring pressed pawl 53, engaging ahorizontally rotatable ratchet wheel 54, having teeth for more thanonehalt' of its circumference, while the remainder is smooth. Thisratchet wheel is rigidly mounted upon a vertical rotatable shaft 55,projecting above the box 10, and hav-' mg a horizontally arranged cam 56rigidly mounted thereon. The ratchet wheel 54, Figure 4, -has a link 57,arranged there-beneath, and pivoted thereto, and this link is pivotallyconnected with a slide rod 58, op-- erat-ing'within a guide 59. Theslide rod 58 carries a compressible brake shoe 60, to engage anddisengage the brake disk 12.

The numeral 61 designates a stationary shifting'cam, arranged near oneend of the shafts 18 and19, and 62 designates a second stationaryshifting cam, arranged near the opposite end of the shafts 18 and 19.These cams have upper inclined faces 63. The

cams 61 and 62 are disposed upon opposite sides of the guide shaft 26,and the cam 61 is arranged in the path of travel of a spring pressed pin64, carried by the feed arm 41, while the cam 62 is arranged in the pathof travel of a spring pressed pin 65, carried by the feed arm 41.Thepins 64 and 65 are disposed, upon opposite sides of the tubularextension 39, as shown.

The carriage 28 is provided with a lateral extension 70, to which ispivoted a depending trip 71, having a knee joint therewith. This tripislfree to swing to the right, but is rigid with respect to swingingmovement to the left, Figure 4.'

The numeral 72 designates the transmitter of a telephone of the. usualconstruction, and .a tube 73 is secured upon this transmitter and leadsto the diaphragm casing 32.

. In Figure 6, the numeral 74 designates the hook of the telephone,which closes the talking circuit at the points 75, when the reciver israised. The receiver may remain upon the hook, and wires 76 and 77 areconnected across the points 75, and lead to stationary contacts 78 and79, carried by the, arm 31, and insulated therefrom. It will be seenthat the talking circuit will be closed, as if the receiver were raised,when.

the contacts 78 and 79 are electrically connected. These contacts areelectrically connected by means of a swinging contact 80, movableinto.and out of engagement therewith, and this swinging contact isrigidly mounted upon the rock shaft 36, pivoted in places upon thecylinder 13 a record containing the desired message, and the eleravagesments of the machine are in the position, as shown in Figure 1. Thecarriage 28 has been shifted to the left, to approach the end of thereverse travel, but the head 43 still engages the reverse screw 19. Thebrake element 60 now holds the brake disk 12 against rotation. When theringing circuit is closed, magnet 50 is energized, and the armature 51is oscillated, and the ratchet wheel 54 turned. This movement of theratchet wheel withdraws the brake element from the brake disk 12, andthemotor is set in action. The carriage 28 now completes its movement tothe left, the pin 64 riding up the shifting cam 61, and this shifts thefeed bar 41 upon its pivot, causing head 43 to disengage reverse screw19, and head 42 to engage feed screw 18. When this occurs, link 38 isdrawn rearwardly and the bell-crank lever 35 is swung downwardly,

ing circuit isclosed. The head 42-engaging the feed screw 18, causes thecarriage 28 to travel to the right, in its feeding movement, until thepin 65 rides upon the shifting cam 62, at which time the feedingmovement is stopped. The feed bar 41 is again shifted so that the head42 disengages the screw 18 and the head 43 engages the screw 19. Thereverse movement of the carriage will now occur, and the trip 71 willengage the cam 56, and turn the same in the direction of its arrow. Thiscam turns-the ratchet wheel 54, and by the time the carriage approachesthe end of its reverse movement, the brake 'element 60 will engage thebrake disk 12,

sorted to, without departing from the spirit of my invention, or thescope of the subjoined claims.

Having thus described my invention, I claim:
